Black dots on the back of your hand are cancer signals?

Black spots on the back of the hand may be cancer signals, but do not rule out other causes.

Clinically common skin cancer is melanoma. Common symptoms of this tumor are changes in the original moles or new pigmented spots on the skin. If melanoma occurs on the back of the hand, there may be black spots on the skin. But other factors can also cause this situation, such as moles, pigmentation after inflammation, etc. Therefore, cancer cannot be judged solely based on black spots on the back of the hand.

If black spots appear on the back of the hand, suspected to be related to cancer, you can go to the hospital for relevant examinations to confirm the diagnosis, such as physical examination, tumor marker examination, skin biopsy, etc.
